(unipolar mood disorders)
2. Bipolar and Related Disorders
4
Magnitude of Mood Disorders
Mood disorders are one of the most common
man kind illnesses.
WHO has ranked major depression the 4
th
among the list of the most urgent health problems
worldwide.
Depressive disorder affects one out of five
women & one out of ten men during their lives.
5
Magnitude…
Bipolar disorders constitute at least 5% in GP.
People affected by mood disorders are at high
risk for suicide & no less than 15% of them
completed suicide.
Many people with mood disorders are disabled.
6
Incidence and Prevalence
Major depressive episode= 5-17 % TP
Dysthymic disorder= 3-6 %
Bipolar disorder = 2.6-7.8 %
7
Depression across different age group
Kids
May pretend to be sick,
Worry that a parent is going to die,
poorly in school performance , and refuse to go to
school, or
exhibit behavioural problems (Irritability).
Older people
More willing to discuss the physical
manifestations of depression, instead of emotional
difficulties.
8
Etiology
There is no single known cause for mood d/os
Biological Factors
Neurotransmitters
NE, DA, 5-HT & histamine disturbance
Thyroid Axis Activity
5 to 10 % of people evaluated for depression have
previously undetected thyroid dysfunction, as
reflected by an elevated basal thyroid-
stimulating hormone (TSH) level.
9
Etiology…
Genetic Factors
Psychosocial Factors
Life Events and Environmental Stress
Psychodynamic Factors in Depression
10
1. Depressive Related disorders
1)Disruptive mood dysregulation disorder
2)Major depressive disorder
3)Persistent depressive disorder (dysthymia)
4)Premenstrual dysphoric disorder
5)Substance/medication-induced depressive d/o,
6)Depressive disorder due to another medical
condition
7)Other specified depressive disorder
8)Unspecified depressive disorder.
11
1. Major Depressive Disorder (MDD)
DSM-5 criteria for MDD
A. Five (or more) of the following present during
the same 2-week period and represent a change
from previous functioning;
At least one of the symptoms is either:
(1) depressed mood or (2) loss of
interest/pleasure.
Note: Do not include symptoms that are clearly
attributable to another medical condition.
12
MDD…
1.Depressed mood most of the day/nearly every day
2.Markedly diminished interest or pleasure
3.Significant weight loss when not dieting or weight
gain or decrease or increase in appetite
4.Insomnia or hypersomnia nearly every day.

6.Fatigue or loss of energy
7.Feelings of worthlessness or excessive or
inappropriate guilt
8.Diminished ability to think or concentrate
9.Recurrent thoughts of death (suicidal ideation)
13
MDD…
B. The symptoms cause clinically significant
distress or impairment
C. The episode is not attributable to the
physiological effects of a substance or another
medical condition.
Note: Criteria A-C represent MDE.
14
2. Persistent Depressive Disorder (Dysthymia)
New in DSM-5
Include both the DSM-IV TR diagnostic categories of:
A. Chronic MDD and
B. Dysthymia:
Long-standing, depression of at least two years
Fluctuating,
Low-grade depression
Experienced as part of the habitual
A more chronic form of depression,
Diagnosed when the mood disturbance continues for 2 yrs
15Double depression
Management
Hospitalization or out patient
A.Pharmacotherapy (Antidepressants)
B.Psychotherapy (psychosocial therapy)
CBT-cognitive behavioural therapy
IPT- interpersonal therapy
C.ECT –electroconvulsive therapy
Pharmacotherapy +psychtherapy most effective Rx.
16
Antidepressants
Increase levels of serotonin and/or NE
At least 2-5 weeks to work (trial unsuccessful)
65-70% of those on medication got improved
40% will stop taking drugs due to side effects
Relapse rate after going off/ stopping
medications is 50%
17
Types of Antidepressants
1. Selective Serotonin Reuptake Inhibitors (SSRIs)
Fluoxetine (prozac) preparation ,10mg & 20mg
dose -10mg to 80mg
Sertraline -preparation 25, 50 ,100mg
dose 50-100mg po
2. Tricyclic Antidepressant (TCA)
Block reuptake of NE (to a lesser extent)& serotonin
Amitriptyline, Imipramine
18
Maintenance treatment
Aim: prevention of new mood episodes/ recurrences
Should be maintained for at least 6 months
Taper the dose gradually over 1 to 2 weeks
Withdrawal before 3 months
Always results in the return of the symptoms.
Patients tend to have more frequent episodes that last
longer.
19
ECT
For depression that doesn’t respond to other Rxs
Exact mechanism of action is unknown
Treatments every other day for total of 6-10 Rxs
Effective
Side effects: short-term memory loss
20
Course and prognosis
Depression is an episodic illness
Disappear by itself but recur unless treated well
If untreated,
20% recover within 3 mths, 80% with in 1 year
Risk of another episode increases with
each episode
50%after 1 episode
70%after 2

23
A. Bipolar I disorder (BP-I)
DSM-5 Diagnostic Criteria
Criteria have been met for at least one manic episode
(Criteria A-D under “Manic Episode” below)
The manic episode may have been preceded by and
may be followed by hypomanic or MDEs.
MDEs are common in BP-I disorder but are not
required for the Dx of BP-I disorder (mixed episode?).
24
Manic Episode
A. Abnormally and persistently elevated, expansive
or irritable mood & increased goal-directed activity or
energy, lasting at least 1 week and present most of
the day (any duration if hospitalization is necessary).
B. Three (or more) of the following symptoms

27
Hypomanic Episode
A. Abnormally and persistently elevated,
expansive or irritable mood & increased goal-directed
activity or energy, lasting at least 4 consecutive
days and present most of the day
B. ≥ 3 from Criteria-B of manic episodes (four if
the mood is only irritable) have persisted, represent
a noticeable change from usual behaviour
28
Hypomanic Episode…
C. Unequivocal change in functioning, uncharacteristic
of the individual when not symptomatic.
D. The disturbance in mood and the change in
functioning are observable by others.
E. The episode is not severe enough to cause
marked impairment or to necessitate hospitalization.
If there are psychotic features, the episode is, manic.

effects of a substance.
29
B. Bipolar II Disorder
A. At least one hypomanic episode and at least one MDE
B. There has never been a manic episode.
C. The occurrence of the hypomanic episode(s) and MDEs is
not better explained by psychotic disorders.
D. The symptoms of depression or the unpredictability
caused by frequent alternation between periods of
depression and hypomania causes:
clinically significant distress or impairment in social,
occupational, or other important areas of functioning.
30
C. Cyclothymic Disorder
A. For at least 2 years (at least 1 year in children
and adolescents); numerous periods with:
1)hypomanic symptoms that do not meet criteria for
a manic episode and
2)depressive Sxs that do not meet criteria for a MDE.

the hypomanic and depressive periods have been
present for at least half the time and
without symptoms not for > 2 months at a time.
C. Criteria for a MDE/ME/HME have never been met.
31

hyperthyroidism).
F. The symptoms cause clinically significant
distress or impairment in social, occupational,
or other important areas of functioning.
Specify if:
With anxious distress
15-50% risk of developing into Bipolar Disorder

Management of
Bipolar Disorders
33
Management…
1. Mood stabilizers:
Indications:
Bipolar, cyclothymia, schizoaffective, impulse control
Classes: Lithium and anticonvulsants
2. Antipsychotics
3. Psychotherapy
34
Management…
I. Lithium
best known treatment
Not sure how it works
Side effects
Excessive thirst and urination, eventual
damage to kidneys and thyroid
Blood levels must be carefully monitored
Effective
30-60%respond well initially
35
Management…
II. Atypical and Typical Antipsychotics
All of the atypical antipsychotics have
demonstrated anti-manic efficacy.
Olanzapine, risperidone, quetiapine,
ziprasidone, and aripiprazole.
Older agents, such as haloperidol ,and CPZ.
36
Management…
III. Psychosocial treatment
Family therapy:
